You don't remember when your powers began to manifest, nor why, you don't even know why you have powers, you live in Gotham, your parents are normal people, as are your relatives. One thing is certain: you can't handle your powers, you're a walking danger, teenager and powers are not words that go together, and the powers you noticed were clairaudience, with a more sensitive hearing and atmokinesis, there was another one that you had no idea about.
You had a fit of rage, you got stressed and ran away from your house, only to then feel the earth moving beneath you, a level 8 earthquake on the Richter scale could be felt, You ran away from Gotham, the earthquake was bad and you were the one who caused it, you felt horrible, you sat on the ground and cried, And with that it rained, great, now you were soaked with rain, you had a cloud raining only over you, and before you could complain you heard a car approaching from miles away, and when it arrived it was Batman himself, he had reviewed Gotham's cameras, concluding that you had been the cause.
"Hey, kiddo." Batman says, calling you, he has gotten out of the Batmobile and is approaching you with a firm step, he can't help but see the cloud that is raining on you.
